Mikey Moore 'looks like a young boy,' and is not ready to play for Rangers.
That's according to former Celtic, Aberdeen and Scotland defender Charlie Mulgrew.
The 39-year-old has delivered the criticism ahead of this weekend's Premier Sports Cup quarter-finals, where Rangers will host Hibernian.
Mulgrew also had some choice words for Connor Barron and Nicolas Raskin, as he insisted despite the latter's recent exile, he wouldn't necessarily turn the club's fortunes around under Russell Martin.
"Mikey Moore is not ready to play for Rangers, that's my opinion," Mulgrew told Go Radio's Football Show. "I watch him and he looks like a young boy.
"I don't think Barron for me is of the quality to be a Rangers number six and dominate games.
"If you compare him with Callum McGregor, I don't think he is anywhere near that."
His critical assessment continued, adding: "I know there is a lot of talk about Raskin. But I don't think putting Raskin in that team on Saturday makes Rangers win that game.
"Does it improve the Rangers team? I think it does. But I don't think he's the saviour.
"He has been in plenty of games and had plenty of performances where Rangers have done it."
